  • (B) Relaxation of the compensatory vasoconstriction
  • (C) Hypoglycemia
  • (D) Bronchial hyperresponsiveness

12 >>Which of the following statements concerning central sleep apnea (CSA) is true? ?

  • (A) CSA is more common than obstructive sleep apnea (OSA) in patients with heart failure
  • (B) Daytime hypercapnia is not seen in patients with CSA.
  • (C) Obesity is a common finding
  • (D) CPAP is not effective in treating patients with CSA as opposed to the treatment of patients with OSA.

13 >>A patient with lymphoma who is known to excrete 1.5 g urinary protein per day has a negative dipstick evaluation for urinary protein. The reason for the seeming inconsistency is ?

  • (A) the size of the excreted protein is too small to be picked up by the test strip
  • (B) the urine is not concentrated enough
  • (C) only heavy chain sequences are recognized by the test strip
